Loss of Performance. The oils from our skin will breakdown the silicone, plastic and rubber used in CPAP masks making them less efficient over time.
Discoloration. If parts of your CPAP mask, tubing or water chamber are turning yellow or cloudy it is time to replace them. Those are clear signs of dirt build-up that can’t be washed away.
Odour. If it’s funky, it needs to go! Even if you clean them regularly, CPAP machines can build up mould and mildew inside of them. That could mean you are breathing in bacteria and pathogens when you sleep.
Irritated Skin. There are a number of reasons why you might be breaking out in a rash or have irritated skin; sometimes your mask might be too tight. But a buildup of facial oils on your CPAP mask could cause irritation too.
